Using A Black Bag For Yamadori Bonsai Video

This video illustrates further the method for recovering newly collected deciduous yamadori bonsai (as well as weak trees), using a cheap black plastic bag.

The use of the bag creates a very humid environment immediately around the trunk and opening leaves, encouraging better budding-out as well as protection for the newly opened leaves while the tree forms new roots. It also discourages tree species that have a tendency to sucker from the base instead of higher up on the trunk.

Ideally, apply the black bag in early Spring, however, it is never too late to apply to any of your trees that are struggling.
